			G1 UVS AWG highlights

The G1 UVS Jovian atmosphere observations focus on 4 types of activities:

1) GRS Feature Track Campaign: 6 observations.
	G1JUFTKR2E12,13,22,23,32,33 observe the GRS in conjunction with the 
	AWG GRS campaign. The UVS objective is to supplement the campaign with
	measurements of the spectral (i.e., compositional) features of 
	the GRS and its vecinity. (RTS only)

2) Auroral studies: 3 observations investigate Jovian auroral processes.
	a) G1JUEWMAPS01 is an LPW recorded, 1/2 hour observation of the southern
	auroral region, including the footprint of the Io fluxtube. 
	Precipitating electron energies, as they impact the upper atmosphere
	hydrogen, will be derived. This observation is planned in 
	collaboration with near-simultaneous HST Jovian auroral observations 
	by John Clarke of Univ. of Michigan. 
	b) G1JUAURMAP01, also in a campaign with HST observations, will 
	observe the southern auroral region asymmetries between dayside
	and nightside aurorae. (RTS only)
	c) G1JUFIXTMD01 will observe northern auroral activity in a 
	unique look at precipitating electron energies as they vary with
	longitude during 1 full Jupiter day (10 hours). (RTS only)

3) Upper atmosphere and global energy studies: 2 observations.
	G1JUFIXLON01 and G1JUDRKMAP01 both measure the characteristics of 
	the upper atmosphere hydrogen on the darkside of the planet (i.e., 
	without the effects of solar illumination) in order to develop a 
	global map of equatorial hydrogen distribution during the mission
	for global energy budget studies. (RTS only)

4) calibration: 2 observations:
	a) G1HUSTRCAL01 will perform a UVS calibration on the star
	delta-Scorpii as one of two calibrations during the mission 
	(also to be observed in C9). (RTS only)
	b) G1JURADMON01 is an LPW recorded, 1 RIM observation that will 
	perform a radiation monitor test at 11 Rj. These data will be
	compared to data collected from the sky background just off the
	star in G1HUSTRCAL01 to quantify radiation effects upon the
	instrument far and close to Jupiter.
